PAPER VESSEL.

Specification of Letters Patent.

Patented Jan. 21, 1908.

Application filed March 7. 1906. Serial No. 304.632.

T 0 all whom it may concern:

Be it known that I, BERroN I. BIKE, a citizen of the United States,residing at Dayton, in the county of Montgomery and State of Ohio, haveinvented certain new and useful Improvements in Paper Vessels; and I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters and figures of referencemarked thereon, which form a part of this specification.

This invention relates to new and useful improvements in paper vessels.

The object of the invention is to provide a paper vessel so constructedthat the mouth thereof will remain closed in a most effectual mannerwithout the employment 9f eyelets or other retaining means. The closureflaps consist of folds of substantially uniform dilnensions whichoverlap each other in closing the mouth of the vessel, and join endextensions the natural resiliency of which exert a pressure on saidclosure flaps to maintain them snugly in their overlapped positions, andalso the end extensions are likewise overlapped in a substantial mannerso that leakage through the mouth of the vessel at any point isprevented.

In the accompanying drawings,-Figure I, is a plan view of the blank fromwhich the vessel is formed. Fig. II, is a perspective view of the upperend of the mouth of the vessel showing the same closed by theoverlapping closure flaps which join the end extensions which arelikewise overlapped in a substantial manner. Fig. III, is an elevationof the inner side of the vessel showing the triangular folds on theinner side and the closure flaps and end extensions open.

In a detail description of the invention, similar reference charactersindicate corresponding parts.

The vessel is constructed of a suitable quality of manila paper out andscored in a mannerto form the vessel as shown in the view of the blankgiven. in the drawings.

When folded, 1 designates the bottom; 2 2 the outer opposite side walls,and 3 3 the outer opposite end walls. The side walls 2 2 and the endwalls 3 3 are brought together by inwardly-breaking bellows folds 4 and5 which break u on intervening score,

8 3 on the outside lines to bring the wal s of the vessel.

The score lines between the V 4. and 5 break inwardly, and when theblank is folded to form the vessel, these triangular folds 4 and 5 lieon the inside of and against the side walls 3 3.

Extending from the triangular folds 5 5 are extension folds 6 6 whichform continuations of said triangular folds 5 5 to the top or mouth ofthe vessel, so that when the folds 4 and 5 are placed against the innersides of the walls 3 3, there is a continuous unbroken surface or wallextending from the bottom of the vessel to the top of the end extensions6 6 and thereby the contents of the vessel are prevented from leakingthrough the top of the folds 5 5. I

7 7 designate the closure flaps which extend across the mouth of thevessel and are folded over the mouth of the vessel one upon the other,and are reinforced to strengthen them. These closure flaps 7 7 overlap asubstantial distance in closing the mouth of the vessel and aremaintained closely together when so overlapped without the usualadditional fastening means. The said closure flaps 7 7 have endextension folds 8 8 extending from each end and which join the extensionfolds 6 6 by an intervening score line, and the extension folds 8 8 arelikewise overlapped to a substantial extent to form a complete closureat the top of the vessel on each side or end of the overlapping closureflaps 7 7. When the closure flaps 7 7 are folded inwardly, as in Fig.II, the folds 6 and 8 bend upon score lines 6 6 and lie against eachother snugly, and the folds 8 8 and 6 6forn1 upright extensions whichjoin as before stated theends of the closure flaps 7 7. These uprightextensions so formed by overlapping triangular folds 6 and 8 reach abovethe end walls 3 3, and are not bent over the mouth of the vessel as iscustomary, but stand upright when the vessel is in a serviceablecondition and exert a certain amount of inward pressure upon theoverlapping folds or flaps 7 7 to maintain them in snug contact. It willbe seen from Fig. II, that the bail or handle 10, when placed in anupright position, presses against the outer sides of said upright or endextensions and exerts a certain amount of inward pressure upon saidupright extensions which is instrumental in causing the pressure on theoverlapping closure flaps 7 7 before stated. This inward tension uponsaid upright or end extensions is increasedwhen the vessel is made tocontain a weight, such as the triangular folds commodity placed therein,and while the vessel is being carried in the hand. The folds between thecover flaps 7 7 and the extension folds 8 8 are upon the score lines 88' and said score lines impart a constant outward ress'ure whichmaintains the overlap ing .olds 8 8 in close contact with the outer fdlds 6 6, and'renders unnecessary any means other than this pressure formaintaining said folds in close contact. The same outward pressure alongthe score lines 8 8 also serves to hold one closure fla for example, theouter closure flap 7, in c ose contact with the inner closure flap 7.The natural resiliency of the material manifests itself readily in theinitial operation of closing or overlapping the flaps 7 7.

The side walls 3 3 may be united to the inner rectangular folds 4 and 5in any suitable manner, but the most desirable means consists of asuitable number of wire fasteners 9 which penetrate said parts throughopenings 10 and are clenched on the inner sides of the triangular foldsat the top of the vessel. The wire bail or handle 10 before referred to,is employed and is united to the top of the side walls 3 3 throughcentral openings 10; the ends of said bail 10 also pass through similaropenings 1 in the triangular folds 4 and 5.

From an inspection of the blank as illustrated in Fig. 1, it will beseen that the closureflaps 6 7 and 8 are of the same area and shaperespectively, at both ends of the blank this form an overlapping coverfor the mouth of the vessel, and the end walls of said vessel consistingof two two-ply overlapping folds which fold against a single thicknessof the blank and terminate in top extensions which stand upright andjoin on their inner sides the overlapping cover extensions, the folds ofsaid top extensions overlapping on their inner sides throughout thelengths of said top extensions and thus forming a complete overlappingclosure for the mouth of the vessel from the upper extremity of one ofsaid top extensions to the upper extremity of the other of said topextensions.

In testimony whereof Iafiix my signature, in presence of two witnesses.
